Global floating wind capacity will have grown from less than 200 MW at the end of 2022 to around 61 GW of grid connected capacity by 2035. This activity will require over $250 billion in capital expenditure. Over 75% of the forecast activity is expected to come from four countries. The global forecast translates demand to a requirement to pre-lay more than 6,000 mooring spreads within the forecast period and the hook-up of around 5,400 turbines. The available market for vessel owners, ranging from pure T&I to full floater EPCI scopes of work, amounts to $28-145 billion in the forecast period.

WTIVs have always been fuel-hungry. Now they are being tasked with installations that are further, deeper and heavier.Offshore wind farms continue their march into deeper water, further from shore, with turbines that can now reach more than 270 meters high with blades 120 meters long. Designers and OEMs are pushing efficiency to new levels to contain OPEX on the new-generation jack-up WTIVs taking them up there.Danish ship design firm Knud E. Hansen has chosen specialization for its Atlas A-class WTIV, a smaller derivation of its massive C-class design.
